[PATCH 1/2] driver: support state cleanup

[Joseph Myers]

I've committed as obvious this patch to fix a build failure this 
introduced for targets not defining EXTRA_SPECS, in which case extra_specs 
is not declared.  (nvptx-none was the target for which I came across such 
a failure.)

	* gcc.c (driver::finalize): Only assign to extra_specs if
	[EXTRA_SPECS].
